If you want a UDF to convert those Roman numerals to Arabic:

I don't remember who wrote this, but I grabbed this a few years ago:


Option Explicit
Function Arabic(Roman)
'Declare variables
Dim Arabicvalues() As Integer
Dim convertedvalue As Long
Dim currentchar As String * 1
Dim i As Integer
Dim message As String
Dim numchars As Integer

'Trim argument, get argument length, and redimension array
Roman = LTrim(RTrim(Roman))
numchars = Len(Roman)
If numchars = 0 Then 'if arg is null, we're outta here
Arabic = ""
Exit Function
End If

ReDim Arabicvalues(numchars)
'Convert each Roman character to its Arabic equivalent
'If any character is invalid, display message and exit
For i = 1 To numchars
currentchar = Mid(Roman, i, 1)
Select Case UCase(currentchar)
Case "M": Arabicvalues(i) = 1000
Case "D": Arabicvalues(i) = 500
Case "C": Arabicvalues(i) = 100
Case "L": Arabicvalues(i) = 50
Case "X": Arabicvalues(i) = 10
Case "V": Arabicvalues(i) = 5
Case "I": Arabicvalues(i) = 1
Case Else
Arabic = "Sorry, " & Roman & " is not a valid Roman numeral! "
Exit Function
End Select
Next i

'If any value is less than its neighbor to the right,
'make that value negative
For i = 1 To numchars - 1
If Arabicvalues(i) < Arabicvalues(i + 1) Then
Arabicvalues(i) = Arabicvalues(i) * -1
End If
Next i
'Build Arabic total
For i = 1 To numchars
Arabic = Arabic + Arabicvalues(i)
Next i

End Function

Then you could use a column of helper cells to get the numeric value and sort
your range by that.

Is there any way to sort data using Roman numerals as the "sort by" column?
Excel treats it as text and places IX before V. I can make it work by adding
a column and manually converting the Roman numerals to regular numbers and
sorting on that, but for some of my reports, that too much data to manually
convert.

Come on guys, make me look like a hero!!
